“Captain America: The Winter Soldier” arrives with the promise of bringing to the screen the famous 2005 comic book storyline by writer Ed Brubaker and artist Steve Epting that inspired the name of the Marvel sequel, and the new film certainly will feel like a departure from Joe Johnston’s 2011 hit “Captain America: The First Avenger,” with its World War II-era focus that chronicled the beginning of Steve Rogers’ transformation into the Marvel icon.

The sequel, which is set after the events depicted in 2012’s “The Avengers,” sees Evans’ hero having remained in the employ of S.H.I.E.L.D., occasionally teaming with Scarlett Johansson’s Natasha Romanoff, or Black Widow, on key missions. Yet even as he bonds with a military man named Sam Wilson (Mackie), who has a superhero alter ego all his own, the Falcon, Cap finds himself with few people he can trust as his past quite literally comes back to haunt him in the form of a close friend turned enemy.

At the end of the teaser, Cap can be seen facing off against that foe, the titular Winter Soldier, played by Sebastian Stan.

Using movies such as Robert Redford’s “Three Days of the Condor” as creative guides (Redford appears in “Winter Soldier” as high-ranking S.H.I.E.L.D. official Alexander Pierce), the directors said they aimed to essentially place Steve Rogers inside his own political thriller. Marrying two seemingly disparate film genres was deeply appealing.
